DETAILED DESCRIPTION OF NON-LIMITING EXAMPLE EMBODIMENTS

In game houses such as casinos, while chips are piled to have a high volume and is placed on a game table, there is a problem in that a total amount cannot be correctly read by a reading device for IC tags disposed under the game table, and, when the sensitivity of the reading device is increased, chips placed at a different position (winning/losing depends on the position) is added, and there is a problem in that a total amount of chips at each position cannot be perceived. In addition, in imaging using a camera, there is a problem in that a blind area is generated according to the viewing angle of the camera, or a chip enters a shadow due to overlapping, and thus, there is a problem in that a total amount of chips cannot be perceived.

In addition, according to player's squeeze (a behavior for seeing a card little by little by bending a card facing the back side while enjoying the rank of the card or the like) of a card, which is frequently performed in a Baccarat game, or the like, the card is bent, and there is a problem in that the rank and the suit of the card cannot be determined through an analysis of an image acquired from a camera.

Furthermore, fraud on a game table has been advanced, and there is a new problem in that fraud using an advanced betting method or the like that cannot be found in simple detection of a large winning amount on a game table or the like cannot be found by using a camera or tracking a winning amount. In addition, the prevention of fraud according to a conspiracy of a dealer and a player is not sufficient according to the conventional technology.

In addition, the control device has an artificial intelligence-utilizing or deep-learning structure capable of comparing/calculating match/mismatch of a total input amount of bills according to a dealer's input in the game table for which the dealer is responsible and a total amount of bills according to a result of the image analysis performed by the image analyzing device.

According to a fraud detecting system according to this embodiment, also when a card is bent according to player's squeeze of the card that is frequently performed in a Baccarat game or the like, the rank and the suit of the card can be determined through an image analysis, and a total amount of chips disposed in the blind area or overlapping chips can be perceived together with the position. In addition, fraud at the time of exchange of bills and chips can be detected as well.

Hereinafter, an overview of the whole fraud detecting system in a game house including a plurality of game tables according to a first embodiment of the present invention will be described in more detail.

FIG. 1 is a diagram illustrating an overview of the whole system, the fraud detecting system in a game house including a plurality of game tables 4 includes: a game recording device 11 that records the state of progress of a game performed in the game table 4 as a video including players 6 and a dealer 5 through a plurality of camera devices 2; an image analyzing device 12 that performs an image analysis of the recorded video of the state of process of the game; and a card distributing device 3 that determines and displays a result of winning/losing of each game in the game table 4. The card distributing device 3 is a so-called electronic shooter that has already been used by persons skilled in the art and has rules of a game programmed in advance and has a structure capable of determining winning/losing of a game by reading information of distributed cards C. For example, in a Baccarat game, winning of the baker, winning of a player, or tie (drawn) is determined basically based on the ranks of two to three cards, and a determination result (a result of winning/losing) is displayed in a result display lamp 13.

The fraud detecting system further includes a control device 14 that compares the rank of actual cards according to a result of the image analysis performed by the image analyzing device 12 and a result of winning/losing determined by the card distributing device 3 with each other and detects fraud (mismatch between a sum of ranks of distributed cards and a result of winning/losing) performed in the game table 4. The card distributing device 3 has a structure capable of reading ranks (A, 2 to 10, J, Q, K) and suits (hearts, spades, or the like) of cards C that are manually distributed by the dealer 5, and the control device 14 has a structure capable of determining match/mismatch by collating information of a rank and suites acquired by the image analyzing device 12 (using artificial intelligence) from a video (captured by using the camera device 2) of cards distributed in the game table 4 and information of cards and suits read by the card distributing device 3 with each other. The image analyzing device 12 and the control device 14 of the fraud detecting system have a structure integrally including a computer formed as one body or by a plurality of configurations, a program, and a memory.

The image analyzing device 12 and the control device 14 have an artificial intelligence-utilizing or deep-learning structure capable of acquiring information of ranks of cards also for cards C that are distributed in the game table 4 and are bent or contaminated by the player 6. For a contaminated card C, as illustrated in FIG. 3, there is a situation in which it is difficult to determine clubs or spades. Also in such a case, the suite can be determined by an artificial intelligence-utilizing computer or control system, an analysis and a determination of an image using a deep learning (structure) technology. In addition, also in a case where a card is bent according to a player's squeeze of a card, which is frequently performed in a Baccarat game or the like, by using self-learning of examples of many deformations of images or the like, a suit and a rank of a card before deformation can be recognized according to an artificial intelligence-utilizing computer or control system and a deep learning (structure) technology. The artificial intelligence-utilizing computer or control system and the deep learning (structure) technology are known as a person skilled in the art and can be used, and thus, detailed description thereof will not be presented.

The control device 14 having an artificial intelligence-utilizing or deep learning structure can perceive a position (a player, a banker, or a pair) inside a bet area 8 on which each player 6 bets chips 120, the type (a value of a different amount is assigned to chips 120 for each color) and the number of the bet chips 120 through the camera device 2 and the image analyzing device 12. Not only there is a case where the chip 120 is vertically arranged to be superimposed but also there is a case where the chips are superimposed with deviations as illustrated in FIG. 2A. In such a case, in a case where the camera device 2 is positioned in the direction of an arrow X illustrated in FIG. 2A (or the direction of the chip 120 is relatively in a blind area), as illustrated in FIG. 2B, it is assumed that the chip 120 is not visible (enters a blind area). According to the artificial intelligence-utilizing computer or control system or the deep-learning technology, by using a self-learning function or the like, hidden chip 120 due to a blind area or the like is recognized (there are case where a part of one unit of chips are hidden or a case where the whole chips are hidden), and the number and the like can be correctly perceived.

In this way, since a position (a player, a banker, or a pair) inside the bet area 8 on which the chips 12 are bet and the type (a value of a different amount is assigned to chip 120 for each color) and the number of the bet chips 120 can be perceived, the control device 14 determines whether or not collection (denoted by an arrow L) of the losing chips bet by each player 6 and payment (120W) for winning chips to a player 6W who has won are properly performed according to a result of winning/losing of a game in accordance with a result of winning/losing of the game determined by the card distributing device 3 in each game by analyzing a video of the state of process of the game through the image analyzing device 12. In a case where a determination result acquired through an analysis using the image analyzing device 12 is different from a result (for example, a result of reading using an RFID) of reading using the other means, the intelligent-type control device 14 stores the analysis image and can verify the result later. As a result of the verification, in the case of an error in the intelligent-type control device 14, by using the analysis image as sample data of teacher leaning in the deep-learning technology, the accuracy of the intelligent-type control device 14 can be improved.

The control device 14 can analyze and acquire a total amount of the chips 120 in the chip tray 17 for the dealer 5 in the game table 4 by using the image analyzing device 12 and can compare and calculate whether or not a total amount of the chips 120 inside the tray 17 for the chips 120 has been increased or decreased according to the amount of collection of the losing chips 120 bet by each player 6 and the amount of the payment 120W for winning chips to a player 6W who has won after the end of the game and the settlement based on a result of winning/losing of the game. A total amount of the chips 120 in the chip tray 17 120 may be constantly acquired using means such as an RFID, and the control device 14 determines whether or not the increased/decreased amount is correct by analyzing the video of the state of progress of the game through the image analyzing device 12.

For this, the artificial intelligence-type or deep-leaning structure is also used.

In this example, since fraud or a mistake is detected based on a result of winning/losing of a game, information of the type of bet chip 120, the position (a player, a banker, or a pair) inside the bet area 8 on which the chips 120 are bet, and the amount of the chips 120, and an increased/decreased amount of the chips 120 in the chip tray 17 after the end of the collection of losing chips and the repayment for the won chips 120 without acquiring the movement of the chips 120 after the end of the game, that is, whether the bet chips 120 has been moved to the player side or the dealer side.

For example, in the case of Baccarat, a result of winning/losing of a game can be determined based on rules of Baccarat by reading ranks of cards C delivered in that game by the card distributing device 3. In addition, a result of winning/losing of a game can be determined also by imaging an area on the game table 4 by using the camera device 2, analyzing the image using the image analyzing device 12, and collating a result of the analysis with the rules of the game by using the control device 14. In such a case, a winning/losing result determining device is configured by the camera device 2, the image analyzing device 12, and the control device 14. The information of a player of each play position 7, the type of bet chip 120, the position (a player, a banker, or a pair) inside the bet area 8 on which the chips 120 is bet, and the amount of the chips 120 is acquired by imaging the chips 120 placed on the bet area 8 by using the camera device 2 and analyzing the image for each play position 7 by using the image analyzing device 12.

In addition, an increased/decreased amount of chips 120 in the chip tray 17 before and after the collection of losing chips 120 and the repayment for winning chips 120 can be calculated by comparing a total amount of the chips 120 disposed inside the chip tray 17 before the collection of losing chips 120 and the repayment for won chips 120 with a total amount of the chips 120 disposed inside the chip tray 17 after the collection of losing chips 120 and the repayment for won chips 120.

The total amount of the chips 120 disposed inside the chip tray 17 before the collection of losing chips 120 and the repayment for won chips 120 and the total amount of the chips 120 disposed inside the chip tray 17 after the collection of losing chips 120 and the repayment for won chips 120 can be detected by imaging the chip tray 17 housing the chips 120 using the camera device 2 and analyzing the image using the image analyzing device 12. In addition, by embedding an RFID representing the amount inside chips 120 and arranging an RFID reader in the chip tray 17, a total amount of the chips 120 housed in the chip tray 17 may be configured to be detected.

For example, it is assumed that the total amount of the chips 120 disposed on the chip tray 17 before the start of a game is Bb, and the total amount of the chips 120 disposed on the chip tray 17 after the game ends, and the collection of losing chips 120 and the re-payment for winning chips 120 is Ba. In addition, in this game, a total amount of all the play positions 7 of chips 120 that is bet on the player area is bp, a total amount of all the play positions 7 of chips 120 that is bet on the banker area is bb, and a total amount of all the play positions 7 of chips 120 that is bet on a tie area is bt. For example, in a case where a result of winning/losing of a game is the winning of the banker, Ba−Bb=bp−bb+bt needs to be satisfied. Alternatively, the total amount Ba of the chips 120 of the chip tray 17 after the end of the game needs to be (Bb+bp−bb+bt). Otherwise, it can be determined that there is fraud or a mistake in the collection or repayment of the chips.

FIG. 13A is a diagram illustrating details of a chip tray according to this embodiment, and FIG. 13B is a diagram illustrating another example of a chip tray. In the chip tray 17, a collection chip tray 171 that is used for collecting and temporarily storing chips 120L that are bet by a losing player 6L and a repayment chip tray 172 for chips 120W that are used for storing chips 120L to be re-payed are arranged. The image analyzing device 12 and the control device 14 acquire the position, the type, and the number of chips 120L that are bet by the losing player 6L and calculates an increased amount (an amount of chips 120 to be present in the collection chip tray 171) of chips 0L in the game. In addition, the image analyzing device 12 and the control device 14 acquires a real total amount of chips 120 in the chip tray 171 after the collection and compare a total amount with the real total amount to determine whether or not there is a difference therebetween.

In addition, for the repayment of chips 120W for a winning player 6W, by using chips 120 that is present in the repayment chip tray 172, a sufficient time can be secured for the image analyzing device 12 and the control device 14 to acquire a real total amount of chips 120 in the collection chip tray 171 after collection.

As illustrated in FIG. 1, the game table 4 includes a disposal area 41 and/or a disposal slot 42 used for disposing cards C used in a game. When a game ends, the cards C used in the game are collected and are put into the disposal area 41 or the disposal slot 42 on the game table 4.

The game table 4 further includes a marker 43 representing winning/losing of a game.

FIG. 4A is a plan view illustrating the front side of a marker, and FIG. 4B is a plan view illustrating the back side of a marker. In a Baccarat game, two types of a marker 43 a representing the winning of the player and a marker 43 b representing the winning of the banker are used, and, when a result of a game comes out, the dealer 5 overturns the marker of the winning side out of the player or the banker. In this way, winning/losing of a game is represented on the table to be easily understood. The overturned marker is returned to the original state by the dealer 5 after the collection and the repayment of chips 120. By returning the marker to the original state, it also represents a state in which a next game can be started.

As above, in this embodiment, the control device 14 calculates the amount of bet chips on the game table 4 and a balance of chips from a result of winning/losing of a game for each game and verifies an increased amount of the balance of chips inside the chip tray 17 after the game. When a difference is detected in this verification, the control device 14 generates an alarm or adds recording of an indication thereof in the recording of a video captured by the camera device 2. A casino operator can peruse the reason for the difference by checking the video.

The fraud detecting system according to this embodiment adds/subtracts an increased/decreased amount of chips in a game calculated based on the positions, the types, and the numbers of chips 120 that is bet by all the players 6 in the game and a result of winning/losing of the game acquired by the winning/losing result determining device to/from a total amount of chips 120 in the chip tray 17 before a settlement of each game, compares a total amount of chips 120 to be present in the chip tray 17 after the settlement at the time of the end of the game with a real total amount of chips 120 in the chip tray 17 at the time of end of the game that is acquired through the image analyzing device 12, and determines whether or not there is a difference between a total amount and a real total amount.

The control device 14 acquires the position, the type, and the number of chips that is bet by each player through the image analyzing device 12, acquires a real total amount of chips placed in the chip tray when all the collections of losing chips bet by each player end, compares a total amount of chips 120 to be present in the chip tray 17, which is acquired by adding an increased amount in the chip tray 17 in the game based on the positions, the types, and the numbers of chips bet by losing players to a total amount of chips placed in the chip tray before a settlement of each game, with a real total amount of chips 120 placed in the chip tray 17, and determines whether or not there is a difference between the total amount and the real total amount.

In a case where the control device 14 compares a total amount of chips 120 to be present in the chip tray 17, which is acquired by adding an increased amount in the chip tray 17 in the game based on the positions, the types, and the numbers of chips 120 bet by losing players to a total amount of chips 120 placed in the chip tray 17 before a settlement of each game, with a real total amount of the chips 120 placed in the chip tray 17, and determines that there is no difference between the total amount and the real total amount, and compares a total amount to be present in the chip tray 17 after the settlement at the time of end of the game with a real total amount of chips 120 placed in the chip tray 17 at the time of end of the game acquired through the image analyzing device 12, and determines that there is a difference between the total amount and the real total amount, the control device 14 determines a mistake in the payment and generates a payment error signal used for giving a notification of the mistake in the payment.

In the chip tray 17, the collection chip tray 171 that collects and temporarily stores chips 120 bet by losing players is arranged, and the image analyzing device 12 compares a total amount of chips 120 to be present in the collection chip tray 171, which is acquired by adding an increased amount of chips 120 in the game that is calculated based on the positions, the types, and the numbers of the chips 120L bet by losing players, with a real total amount of the chips 120 placed in the chip tray 171, and determines whether or not there is a difference between the total amount and the real total amount.

When the control device 14 determines a difference in the real total amount of the chips 120 acquired from the chip tray 17 for the dealer 5 of the game table 4 not corresponding to the increased/decreased amount of the chips calculated based on the amount of chips bet by all the players and a result of winning/losing of the game, the game recording device 11 assigns an index or time to the acquired video or can reproduced with a collection scene or a payment scene of the chips 120 specified such that the recording of the game in which the difference occurs can be analyzed by the game recording device 11.

In this way, the control device 14 acquires a total amount of chips (chips) placed in the chip tray 17 after a settlement at the time of end of a game through the image analyzing device 12. In this case, the determination of “after the settlement” is when one of “1)” to 4)” described below occurs.

1) when repayment for won chips 120 (won chips) ends.

2) when cards C used in the game are collected and are disposed in the disposal area or the disposal slot of the table.

3) when a predetermined button accompanying the winning/losing result determining device is pressed.

4) when the marker 43 representing winning/losing is returned to the original state.

In the management system of the table game, the management control device images the positions, the types, and the numbers of chips that is placed by game participants in each game when any one of 1) to 3) described below is detected.

1) when the card distributing device detects that a first card is drawn.

2) before and after drawing.

3) after the management control device recognizes a dealer's bet end sign.

In addition, the control device 14 has an artificial intelligence-utilizing or deep-learning structure capable of acquiring the position (a position for betting on the player, the banker, or the fair) and the amount (the types and numbers) of bet chips at each player position 7 of the game table 4, comparing a winning/losing history of each player 6 and the amount (won amount) of acquired chips that can be acquired based on the result of winning/losing of each game with statistical data of many (big data) games in the past, and extracting an abnormal situation (set in the casino).

Typically, the control device 14 is included which has an artificial intelligence-utilizing or deep-learning structure capable of extracting an occurrence of a won amount of a certain amount (one million dollars) or more and an abnormal situation in which, in a play position 7 of a specific game table 4, a state in which the amount of bet chips is small at the time of losing a game, and the amount of bet chips is large at the time of winning a game is continued for several games and is determined as an abnormal situation based on a comparison with statistical data (big data or the like) of games in the past.

In addition, the control device 14 (integrated with the image analyzing device 12) of the fraud detecting system has a structure capable of extracting an abnormal situation or specifying an individual player 6 at the play position 7 at which winning of a predetermined amount of more is acquired. In such specifying of a player 6, the image of each face is specified with a profit and an identify number (an ID or the like) assigned thereto in the image analyzing device 12. Then, the control device 14 has a warning function for giving a notification of the presence of a specific player in another game table when the specified player 6 leaves a seat and arrives at the another game table. More specifically, a notice is given to a pit manager managing each game table 4 or each table staff (or a dealer), wherein further prevention of an abnormal phenomenon is achieved.

The control device 14 includes a database recording a history of exchange of bills K and chips 120, refers to the database at the interval of a predetermined time or in units of one day and determines through a comparison whether or not the amount of chips 120 acquired in the chip tray 17 for the dealer 5 of the game table 4 has been increased or decreased according to a payed amount of chips 120 corresponding to exchanged bills K or a total amount of payment of bills K corresponding to exchanged chips 120.

In addition, a winning/losing history of each play position 7 and the amount (won amount) of acquired chips may be monitored without specifying an individual player 6.

In such a case, while, in a case where each player 6 leaves the seat, the player 6 cannot be tracked, an abnormal situation such as a case where, a state in which the amount of bet chips is small at the time of losing a game at a specific play position 7 of one game table 4, and the amount of bet chips at the time of winning a game is large is continued for several games or the like can be detected. Then, in a case where such a play position 7 is detected, there is a suspicion that there is fraud or a mistake at the play position 7. Then, by verifying a video in which the play position 7 is imaged, a fraud or a mistake can be found.

More specifically, the camera device 2 is mounted to image at least chips 120 placed in the bet area 8 of the game table 4. The image analyzing device 12 analyzes images captured by the camera device 2 and detects a position among the positions of the player, the banker, and the tie of the bet area 8 at which chips are placed for each user position 7 and the amount of the placed chips. In addition, the card distributing device 3 also functions as a winning/losing result determining device and determines a result of winning/losing of a game. The control device 14, based on the position (the player, the banker, or the tie) inside the bet area 8 at which the chips 120 are placed and the result of winning/losing of the game, records monitors) a winning/losing history for each play position 7 and the amount (an acquired amount of the chips) of the chips that has been acquired. Here, any one of the winning/losing history and the acquired amount of the chips may be recorded. In a case where the winning/losing history/or the acquired amount of the chips is in an abnormal situation (set in the casino) when compared with the statistical data of many (big data) games in the past, the control device 14 specifies this player position 7 as a play position at which a suspicion of fraud is present.

In a case where there is a suspicion of fraud for a specific player position 7, the fraud detecting system may be configured to generate an alarm (light, a sound, or a vibration) such that at least the dealer gets near at the time point. In this way, a game thereafter is stopped at least at the place or the like, and the continuation of fraud can be blocked. In addition, information representing a suspicion of fraud may be added to a video that is captured and recorded by the camera device 2. Accordingly, by checking the video, the cause of the suspicion of fraud can be investigated.

The fraud detecting system in a game house including a game table according to this embodiment further has a function of performing an inspection at the time of exchange of bills and chips that is frequently performed in the game table 4. In a game house such as a casino, before a game, a player 6 exchanges bills (cash or the like) and chips at a predetermined chip clearing house. However, when all the chips are used, the player 6 can continue the game by exchanging cash (bills) with chips 120 on the game table (a Baccarat table or the like) without leaving the seat from the game table 4. However, here, there is a chance for fraud between the dealer 5 and the player. The exchange of cash (bills) for chips 120 on a game table (for example, a Baccarat table or the like) needs to be performed when a game does not advance. In order to determine winning/losing of a game, the card distributing device 3 can detect the start of dealing of cards and the end of dealing (a time period for determining winning/losing). For this reason, the card distributing device 3 detects a situation other than the distribution (dealing) of cards, and the control device 14 detects exchange of bills and chips 120 on the game table 4 in a situation other than the dealing of cards (illustrated in FIG. 5).

Being in the middle of the dealing (or any other situation) of cards can be detected based on information acquired from the operation of the card distributing device 3 or the dealer 5.

The control device 14 can recognize the number and the amount of bills by performing an image analysis of the surfaces of the bills K. In addition, in the game table 4, it is determined whether or not bills K to be exchanged for chips 120 are genuine by detecting genuine marks G of the bills by emitting black light. As illustrated in FIG. 5, the control device 14 has an artificial intelligence-utilizing or deep-learning structure verifying the genuine marks G through an image analysis, recognizing a total amount of genuine bills, being capable of recognizing a total amount of chips even in a state in which a plurality of chips come out onto the game table as an exchange target is hidden due to a blind area of the camera device 2, comparing a total amount of the bills K come out onto the game table 4 from a player with a total amount of the chips 120 come out from the dealer 5, and being capable of determining whether or not both the amounts match each other.

The control device 14 has an artificial intelligence-utilizing or deep-leaning structure capable of determining whether or not a total amount of chips 120 placed in the chip tray 17 for the dealer 5 of the game table 4 has been increased/decreased according to a paid amount of chips corresponding to the exchanged bills after a settlement through exchange of the bills and the chips. A case may be considered as well in which the total amount of the chips 120 placed in the chip tray 17 for the dealer 5 is constantly acquired in advance by using RFIDs of chips 120 or the like. In addition, the total amount of the chips 120 housed in the chip tray 17 can be detected by imaging the chip tray 17 housing the chips 120 by using the camera device 2 and analyzing the image using the image analyzing device 12.

In addition, the control device 14 detects whether an increase/decrease in the amount of the chips 120 present inside the chip tray 17 before and after the exchange of bills and the chips matches an exchange amount of the chips as a result of an image analysis on the game table 4. The amount of paid bills may be input by the dealer 5 to the control device 14 through key input or the like or may be specified by imaging an area disposed on the game table 4 in which bills are paid by using the camera device 2 and analyzing the image using the image analyzing device 12.

As described above, the control device 14 determines whether or not a decreased amount of the chips 120 from the chip tray 17 according to the exchange of bills and the chips matches the amount paid to the dealer 5 from players 6. In addition, the control device 14 is an intelligence-type control device capable of determining match/mismatch of an input amount (commonly, according to key input or the like) of bills input by the dealer 5 and a calculated amount of bills that is a result of an image analysis performed by the image analyzing device 12 after the settlement through the exchange of the bills and the chips through a comparison and calculation and may have an artificial intelligence-utilizing or deep-learning structure.

Furthermore, the control device 14 has an artificial intelligence-utilizing or deep-learning structure capable of determining match/mismatch of a total amount of bills according to the input of a dealer in the game table 4 for which the dealer is responsible and a total amount of bills according to a result of an image analysis using the image analyzing device 12 through a comparison and calculation.

The control device 14 determines whether or not the amount of chips 120 perceived in the chip tray 17 for the dealer 5 of the game table 4 has increased/decreased according to a paid amount of chips 120 corresponding to exchanged bills after the exchange of the bills and the chips 120 or a paid amount of bills corresponding to the exchanged chips 120 through a comparison.

The control device 14 is a control device having an artificial intelligence-utilizing or deep-learning structure capable of acquiring information of the types and the numbers of the chips 120 even in a state in which a part of or the whole one unit of chips are hidden when the types and the numbers of the chips 120 are determined.

A management system according to a second embodiment relates to a management system of table games in a game house.

In a game house such as a casino, there are various attempts preventing dealer's mistakes in handling chips. A game house includes monitoring cameras used for monitoring dealer's mistakes in handling chips, and such mistakes are prevented using a determination of mistakes and fraud according to collection and repayment of chips that are different from a result of winning/losing based on images acquired using the monitoring cameras and the like.

Meanwhile, in order to acquire the number and a total amount of chips, it has been proposed to acquire the amount of the chips by attaching an IC tag to each chip.

In a card game monitoring system disclosed in PCT Application Publication No. PCT/JP2015/000171, it is determined whether or not chips place on a game table are collected or re-payed according to a result of winning/losing by performing an image analysis of movement of the chips, and monitoring of dealer's mistakes in handling the chips are performed.

In game houses such as casinos, while chips are piled to have a high volume and is placed on a game table, there is a problem in that a total amount cannot be correctly read by a reading device for IC tags disposed under the game table, and, when the sensitivity of the reading device is increased, chips placed at a different position (winning/losing depends on the position) is added, and there is a problem in that a total amount of chips at each position cannot be perceived. In addition, conventionally, as illustrated in FIG. 7, the pattern of chip (chips for gaming) 9 is complicated, and, when a plurality of chips are piled, there is a problem in that the number of such a pile cannot be accurately acquired using a camera.

Furthermore, fraud on a game table has been advanced, and there is a new problem in that fraud using an advanced betting method or the like that cannot be found in simple detection of a large winning amount on a game table or the like cannot be found by using a camera.

In addition, it is necessary for a dealer to collect or re-paid chips placed on a game table according to a result of winning/losing. In a case this is to be determined by performing an image analysis of the chips, since the pattern of the chip (chips for gaming) is complicated, there is a problem in that it cannot be determined whether or not a dealer correctly performs re-payment when chips corresponding to the bet chips is re-payed by using a currently-existing practical image analyzing technology, and the prevention of mistakes is not sufficient.

In order to solve the various problems described above, a management system of table games according to this embodiment includes: a card distributing device that determines and displays a result of winning/losing of each game in a game table; a measurement device that measures the types and the numbers of chips place on the game table by using a camera; and a management control device that specifies and stores the position, the types, and the numbers of chips placed on the game table by a game participant by using a result of the measurement performed by the measurement device in each game. The chip has a configuration in which a plurality of plastic layers of different colors are stacked, at least a coloring layer is included in the middle, and a stripe pattern in a stacking direction is formed on a side face by employing a multi-layer structure in which white layers or thin-color layers are stacked on both sides of the coloring layer disposed in the middle, and the type of the chip can be specified by using the coloring layer. The management control device has calculation functions of determining a winner and a loser among participants in each game by using a result of winning/losing acquired from the card distributing device and a result of the measurement of the position, the types, and the numbers of the chips placed by each game participant and calculating the balance of the casino side in the game table for each game.

In addition, in the management system, the management control device has a structure including a function of determining the amount of the chips by measuring the number of coloring layers, the white layers, or the thin-color layers of the chips placed by each game participant.

In order to solve the various problems, a chip according to this embodiment has a configuration in which a plurality of plastic layers of different colors are stacked, at least a coloring layer is included in the middle, and a stripe pattern in a stacking direction is formed on a side face by stacking white layers or thin-color layers on both sides of the coloring layer, and the type of the chip can be specified by using the coloring layer.

In addition, in the chip, on the surface of the white layer or the thin-color layer, a print representing the type of the chip is formed, transparent layers are disposed in outermost layers, and each interlayer is thermos-compressed to form a structure of at least five layers.

In addition, in the chip, marks using UV ink or ink (carbon black ink) absorbing infrared rays are arranged on the surfaces of the white-color layers or the thin-color layers, or embossing processing is performed for the transparent layer of the outermost layer, or R processing is performed for the ends of the transparent layers of the outermost layers, or the coloring layer is formed by a plurality of layers, and RFIDs may be built in the coloring layers.

In order to solve the various problems described above, an inspection device inspecting chips according to this embodiment includes: a passage including an inlet and an output through which the chips can pass in a radial direction; a chip type determining device that determines a color of the stripe in the staking direction of the side face by imaging the side face of the chip passing through the passage; a mark reading device that reads a mark, which is formed using the UV ink or the ink (carbon black ink) absorbing infrared rays, arranged on the surface of the passing chip; a print inspecting device that reads a print representing the type arranged on the surface of the chip in a vertical direction with respect to the passage; and a control device of the whole device. The control device is configured to inspect whether or not the type of the chip determined by the chip type determining device matches a content of the print representing the type acquired by the print inspecting device.

According to the system of this embodiment, even in a case where many chips (substitute currency for gaming) are piled up, the number of the chips can be determined, and a total amount of relatively overlapping chips can be acquired based on the position and the color.

Hereinafter, a management system of table games in a game house including a game table according to an embodiment of the present invention will be described. FIG. 6 is a diagram that illustrates an overview of the whole system. The management system of table games in a game house including a plurality of game tables 4 includes: a measurement device 19 including an image analyzing device 18 that records a state of process of a game played in the game table 4 as a video including game participants 6 and a dealer 5 through a plurality of camera devices 2 and performs an image analysis of the recorded video of the state of process of the game; and a card distributing device 3 that determines and displays a result of winning/losing of each game in the game table 4. The card distributing device 3 is a so-called electronic shooter that has already been used by persons skilled in the art and has rules of a game programmed in advance and has a structure capable of determining winning/losing of a game by reading information of distributed cards C. For example, in a Baccarat game, winning of the baker, winning of a player, or tie (drawn) is determined basically based on the ranks of two to three cards, and a determination result (a result of winning/losing) is displayed in a result display lamp 13.

The management control device 14 reads information (ranks and suits) of cards C acquired from the card distributing device 3 and determines a result of winning/losing of each game and determines a winner 6W and a loser 6L among the participants 6 in each game by using a result of measurement of the position, the types, and the numbers of chips 120 placed by the game participants 6.

In addition, the management control device 14 has a calculation function of calculating a balance (an amount acquired by subtracting a total amount of chips 120 that is re-paid to a winner 6W among the participants 6 from a total amount of chips 120 bet by the loser 6L) of the casino side in the game table 1 for each game.

The image analyzing device 18, the measurement device 19, and the management control device 14 of this detection system have a structure integrally including a computer formed as one body or by a plurality of configurations, a program, and a memory.

Next, details of chip used in this detection system will be described. FIG. 8 is a front cross-sectional view of a chip 120 used in this detection system. The chip 120 has a multi-layer structure in which a plurality of plastic layers having different colors are stacked, a coloring layer 121 is included at least in the middle, and white layers 122 or thin-color layers (while not illustrated in the drawing, the layers may be layers of a color that is thinner than that of the coloring layer 121) are stacked on both sides of the coloring layer 121 of the middle.

In this way, by employing a multi-layer structure in which the coloring layer 121 is included, and white layers 122 or thin-color layers (while not illustrated in the drawing, the layers may be layers of a color that is thinner than that of the coloring layer 121) are stacked on both sides of the coloring layer 121 of this middle, as illustrated in FIG. 9A, a stripe pattern is formed on the side face in the stacking direction, and the type of the chip 120 can be specified by changing the color (red, green, yellow, blue, or the like) of the coloring layer 121 for each type (10 points, 20 points, 100 points, 1000 points, and the like) of the chip 120.

The chip 120 is configured as a structure body including the coloring layer 121 and the white layer 122 or the thin-color layer at least in the outer appearance to form a stripe pattern in the axial direction on the side face and has a configuration enabling the type of the chip 120 to be specified using the coloring layer 121. While FIGS. 10A and 10B illustrate different examples, in the examples, the coloring layer 121 and the white layer 122 or the thin-color layer are formed through injection molding, and so-called two-color molding is used in which, first, the coloring layer 121 is molded inside a die for molding (not illustrated in the drawing), and thereafter, the white layer 122 or the thin-color layer is molded.

In addition, as illustrated in FIG. 9B, in the chip 120, prints 123 (100 points or the like) representing the type of the chip 120 are formed on the surfaces (the upper face and the lower face) of the white layer 122. As illustrated in FIG. 8, the transparent layers 124 are disposed in the outermost layers, and each interlayer is thermos-compressed, and a structure of at least five layers is formed. Such chip 120 is formed by using a plastic material having a thin long shape, and layers (the coloring layer 121, the white layer 122, and the transparent layer 124) are thermo-compressed to form a closely adhering state (a structure of five layers or the like) in the state of a long length, and thereafter, holes having a circular shape, a rectangular shape, or the like are formed therein through press or the like.

When a hole is formed through the press, die of mold for punching, and the size of punching are designed, and R processing (round angle) is performed for the ends of the transparent layer 124 of the outermost layer.

That is, in order to manufacture the chip 120, first, a plate-shaped coloring layer 121 formed using plastic and a plate shaped white layer 122 or a thin-color layer formed using plastic are stacked, and a stacked structure body configured by a plurality of plastic layers is formed. Then, drawing patterns are printed on the upper face and the lower face of this stacked structure body, and transparent layers 124 are formed thereon. Then, the layers of the stacked structure body and the transparent layers 124 are heated and pressed to be heated and welded, whereby a chip original plate is generated. Then, punching processing is performed for the chip original plate acquired in this way, whereby a plurality of chips 120 having a predetermined shape are acquired. When this punching processing is performed, R processing is performed for upper and lower angles of the chip 120 using a mold.

In addition, in the chips 120, face codes using the UV ink or ink (carbon black ink) absorbing an infrared rays are arranged on the surface of the white layer 122 (see FIG. 9B). This face codes represent the authenticity of the chip 120, and, when ultraviolet rays (or infrared rays) are emitted thereto, a mark is visible to the eyes, and a combination of the form and the number of the marks represents the authenticity. FIG. 11 is a perspective view of a state in which the chips 120 are stacked up, and a face code M is acquired by combining a long code L and a short code S. In the outermost layers, while transparent layers (print layers) 124 are thermally compressed or formed as coating layers to cover the print 123 and the face code, embossing processing is performed for these transparent layers 124, and the close adherence between the chips 120 is prevented. In addition, in this embodiment, while an example has been described in which face codes are printed on the surfaces of the white layers 122, instead of the face codes or together with the face codes, one or both of a security mark and an optically variable device (OVD) may be printed.

The R processing (R) is performed for the ends of the transparent layers (print layer) 124 of the outermost layer for which the print 123 (100 points or the like), and in the punching process of the chip 120, the surfaces of the white layers 122 are prevented from being deformed to appear on the side face. In addition, it is prevented that a sharp end remains in the chip 120 and damages the hands or the other chip 120.

The coloring layer 121, as illustrated in FIG. 8, may be formed by a plurality of colored layers (three layers in the case illustrated in FIG. 8). Since the plurality of colored layers (three layers in the case illustrated in FIG. 8) are thermos-compressed, a state in which the three-layer structure can be visually observed, as illustrated in FIG. 8, is not formed. However, three layers are illustrated in FIG. 8 for description. In addition, in a middle layer among the three layers of the coloring layer 121, a partly hollowed portion B is arranged, and an RFID 125 is built therein.

In addition, without arranging the hollowed portion B in the coloring layer 121, the RFID 125 may be built in the chip 120 by arranging the RFID 125 between the coloring layer 121 having a flat surface and the white layer 122 having a flat surface and performing thermos-compressing of the coloring layer 121 and the white layer 122 as it is. By configuring at least one of the coloring layer 121 and the white layer 122 using a material such as plastic that can be thermally deformed, out of the coloring layer 121 and the white layer 122 having the RFID 125 interposed therebetween through thermal compression, a plastic layer is thermally deformed, and accordingly, the RFID 125 is tightly fixed between such layers without arranging the hollowed portion B.

FIG. 12 is a perspective explanatory photographic diagram that illustrates a state in which chips of different types are piled up. The management control device 14 images chips 120 placed on the game table 1 by the game participant 6 by using the camera device 2 and measures each area 8 (whether the bet is on the banker, the player, the pair, or the tie) in which the chips 120 are placed by using the measurement device 19 including the image analyzing device 18, and the measurement device 19 (by using information acquired by the image analyzing device 18) analyzes and measures the number and the colors of coloring layers 121 (or the thin-color layers) or white layers 122 of the chips 120 that are stacked in each area and determines the types and the numbers of the chips 120. The management control device 14 performs control of the camera device 2 such that imaging using the camera device 2 is performed when the first card is drawn from the card distributing device, before and after the drawing, or after a dealer's sign representing the end of betting.

The management control device 14 may be a control device having an artificial intelligence-utilizing or deep learning structure. The management control device 14 can perceive the position 8 (a position betting on a player, a banker, or a pair), the types (a value of a different amount is assigned to the chips 120 for each color), and the numbers of the chips 120 that is bet by each participant 6 through the camera device 2 and the image analyzing device 18. The artificial intelligence-utilizing computer or control system can perceive the position 8 (a position betting on a player, a banker, or a pair), the types (a value of a different amount is assigned to the chips for each color), and the numbers of the chips 120 by using a self-learning function or the like in the deep-learning (structure) technology, and thus, according to a result of winning/losing of a game determined by the card distributing device 3 in each game, determines whether or not the collection (denoted using an arrow L) of chips 120 bet by a losing participant 6L and the re-payment (payment (120W)) for winning chips 120 for the winning game participant 6W are appropriately performed according to a result of winning/failure of the game in each game by analyzing a video of the state of progress of the game by using the management control device 14 through the image analyzing device 18.

In such a case, as illustrated in FIG. 11 (compared to conventional chips illustrated in FIG. 7), a stacked multi-layer structure is formed, and a stripe pattern is formed on the side face in the stacking direction, and accordingly, the measurement device 19 including the image analyzing device 18 can accurately perform the measurement of the types and the numbers of chips in an easy manner. In addition, by using an artificial intelligence-utilizing computer or control system and a deep-learning (structure) technology, the analysis and the determination of the image can be performed more accurately. The artificial intelligence-utilizing computer or control system and the deep-learning (structure) technology are known to persons skilled in the art and can be used, and thus, detailed description thereof will be abbreviated.

The management control device 14 can analyze and perceive a total amount of chips 120 in the chip tray 17 for the dealer 5 of the game table 4 by using the image analyzing device 18 and can determine through a comparison and calculation whether or not a total amount of the chips 120 placed inside the chip tray 17 has been increased/decreased according to the collection of the losing chips 120 bet by each game participant 6 and the amount of the payment 120W for winning chips to the winning game participant 6W after the game ends and is settled based on the result of winning/losing of the game. The total amount of the chips 120 in the chip tray 17 may be constantly acquired by using means such as RFIDs, and it is determined whether or not the increased/decreased amount is correct by the management control device 14 by analyzing a video of the state of progress of the game through the image analyzing device 18. For these, an artificial intelligence-utilizing or deep-learning structure may be utilized.

In addition, the management control device 14 may have an artificial intelligence-utilizing or deep-learning structure capable of acquiring the position (a position for betting on the player, the banker, or the fair) and the amount (the types and numbers) of bet chips at each player position 7 of the game table 4, comparing a winning/losing history of each player 6 and the amount (won amount) of acquired chips that can be acquired based on the result of winning/losing of each game with statistical data of many (big data) games in the past, and extracting an abnormal situation (set in the casino). Typically, the management control device 14 is included which has an artificial intelligence-utilizing or deep-learning structure capable of extracting an occurrence of a won amount of a certain amount (one million dollars) or more and an abnormal situation in which, in a play position 7 of a specific game table 4, a state in which the amount of bet chips is small at the time of losing a game, and the amount of bet chips is large at the time of winning a game is continued for several games and is determined as an abnormal situation based on a comparison with statistical data (big data or the like) of games in the past.

The total amount of the chips 120 in the chip tray 17 for the dealer 5 of the game table 4 is settled for the chips 120 bet by each participant 6 after each game, and the management control device 14 has a structure capable of determining through a comparison and calculation whether or not an increase/decrease in the chips that corresponds to a settlement is correct after the settlement.

In the chip tray 17 used for storing the chips 120 for the dealer 5 illustrated in FIG. 6, the types and the numbers of the chips 120 can be determined by analyzing and measuring the numbers and the colors of the coloring layers 121 or the white layers 122 of the chips 120 stacked in the horizontal direction by using the measurement device 19 (by using the information acquired by the image analyzing device 18). The total amount of the chips 120 for the tray 17 for storing chips is constantly (or at predetermined time intervals) acquired in this way. As the management control device 14 has a calculation function of calculating a settlement amount (calculation of a balance of the casino side in the game table 4 (an amount acquired by subtracting a total amount of the chips 120 re-paid to the winner 6W among the participants 6 from a total amount of the chips 120 bet by the loser 6L) of each game for each game (see description presented above), the total amount of the chips 120 of the chip tray 17 is constantly (or at intervals of a predetermined time) is verified. That is, it is verified whether or not an increase/decrease in the chips matches a result of an image analysis performed by the image analyzing device 18 and the settlement amount of each game performed by the dealer 5.

FIG. 13A is a diagram that illustrates details of a chip tray according to this embodiment, and FIG. 13B is a diagram that illustrates another example of tray for the chip. In the chip tray 17, a collection chip tray 171 that is used for collecting and temporarily storing chips 120L that are bet by a losing player 6L and a repayment chip tray 172 120W that are used for storing chips 120L to be re-payed are arranged. The image analyzing device 12 and the control device 14 acquire the position, the type, and the number of chips 120L that is bet by the losing player 6L and calculates an increased amount (an amount of chips 120L to be present in the collection chip tray 171 120) of chips 120L in the game. In addition, the image analyzing device 12 and the control device 14 acquire a real total amount of the chips 120 in the chip tray 171 after the collection and determine whether or not there is a difference between the total amount and the real total amount through a comparison.

Here, the chip tray 17 that is illustrated above has a two-stage structure formed by an upper stage chip tray 17 a and a lower stage chip tray 17 b. FIGS. 14A and 14B are diagrams that illustrate a relation between the chip tray 17 having a two-stage structure and a camera device 2, FIG. 14A illustrates a state in which two stages overlap each other, and FIG. 14B illustrates a state in which two stages are shifted from each other.

Hereinafter, a management system of chip in a game house including a game table according to an embodiment of the present invention will be described with reference the drawings. FIG. 16 is a diagram that illustrates an overview of the whole system. The management system of chip in a game house including a plurality of game tables 4 (only one game table is illustrated in FIG. 16) images the state of progress of a game played in the game table 4 including a game participant 6 and a dealer 5 through a plurality of camera devices 2 and stores and manages the state. Particularly, the management system of chip specifies the types and the numbers of chips 120 used in the game table 4 by analyzing image information acquired by the camera device 2. A side ID 126 is attached to the side face of the chip 120, and the types and the numbers of the chips 120 is acquired by determining the side ID 126 and reading the types and the numbers. In addition, in this specification, a description of “side ID” or “ID” is used not only in the meaning of an ID as a physical entity attached to the side face of the chip 120 but also in the meaning of identification information represented thereby. An ID reading device 53 disposed inside a management control device 50 connected to the camera device 2 specifies a side ID 126 by analyzing image information acquired from the camera device 2. Particularly, the management control device 50 includes a chip determining device 52 specifying the types and the numbers of the chips 120 that is in a horizontally aligned state or in a piled state based on a result of the reading of the side ID 126 acquired by analyzing the image data imaged through the camera device 2 therein.

In addition, the management system according to this embodiment is configured to image chips 120 disposed on a game table 4 by using a plurality of camera devices 2 b-1 and 2 b-2, which have different heights, arranged at predetermined positions in addition to the camera device 2 that images the chips 120 and records an acquired image. The camera device 2 b-1 can image chips 120 disposed at a relatively far position on the game table 4, and the camera device 2 b-2 is configured to image chips 120 disposed relatively close on the game table 4. By performing imaging the two camera devices 2 b-1 and 2 b-2, chips 120 disposed at a place that is in a blind area for one of the camera devices can be imaged as well.

In a plurality of cashiers 60 present in a game house, the chips 120 are exchanged with cash 61 paid by a game participant 6, and, in each cashier 60, chips 120 are stored in a storage 62 storing the chips 120. In each cashier 60 of a game house, chips 120 brought by a game participant 6 is refunded into cash 61. In the game table 4, chips 120 are stored in a game table chip tray 17, and a dealer 5 collects chips 120 bet by a game participant 6 who has lost the game from the table 4 in each game, returns the collected chips 120 to the game table chip tray 17, and then re-pays the chips 120 to a game participant 6 who has won each game. All such exchanges between a game participant 6 and a cashier 60 of a game table or a dealer 5 are imaged and recorded by all the camera devices 2. In the storage 62 or the game table chip tray 17, when there is exchange of chips 120 with a game participant 6, the chips 120 stored in the storage 62 or the game table chip tray 17 increases or decreases. The types and the numbers of the chips 120 stored in the game table chip tray 17 and the storage 62 are monitored at predetermined timing or constantly by the ID reading device 53 and the chip determining device 52 through the camera device 2. The management control device 50 stores the side IDs 126 of all the chips 120 assumed to be used in a game house in the database 51 in advance (the side IDs 126 of all the chips 120 assumed to be used in the game house are registered).

In addition, also in this embodiment, the chip tray 17, as illustrated in FIGS. 14A and 14B, may be configured by an upper chip tray 17 a and a lower chip tray 17 b of upper/lower two stages. In such a case, in the state illustrated in FIG. 14A, the upper chip tray 17 a can be imaged by the camera device 2, and, in the state illustrated in FIG. 14B, the lower chip tray 17 b can be imaged by the camera device 2. In the state illustrated in FIG. 14B, additionally, the upper chip tray 17 a and the lower chip tray 17 b can be imaged by the camera device 2 c simultaneously and also in an individually-identifiable state. In addition, in the state illustrated in FIG. 14B, the upper chip tray 17 a and the lower chip tray 17 b may be separately imaged. Each of the camera devices 2 and 2 c may include a single visible-light camera or a single infrared ray camera corresponding to ink printed for the side ID 126 or a camera capable of performing switching among a plurality of functions of a visible-light camera and an infrared-ray camera corresponding to the printed ink.

In this way, in the game house, by using the database 51, the management control device 50 managing the side IDs 126 associated with chips 120 manages all the side IDs 126 of at least chips 120 present in the game table chip tray 17 and the storage 62 in the database 51 together with the presence information thereof (the storage 62, the game table chip tray 17, in the middle of moving from a backyard (not illustrated in the drawing), held by a game participant 6, or the like). The management control device 50 specifies all the chips 120 disposed in the game table chip tray 17 and the storage 62 by using the side IDs 126 at predetermined timing or constantly, searches the database 51, and determines the following events through the search of the database 51.

1) A side ID 126 that has not been present (or not present) in the database 51 is determined to be newly present.

2) Two or more same IDs are determined to be present.

The management control device 50 has a function of generating an error signal representing an abnormality and giving a notification to a management division or a security division 54 of the game house when the situation of 1) or 2) described above is present. The management control device 50 specifies all the chips 120 disposed in the game table chip tray 17 and the storage 62 at predetermined timing or constantly by using the side IDs 126 and stores all the chips 120 in the database 51 and thus, can determine that 1) a side ID 126 that has not been present (or not present) in the database 51 is newly present and 2) two or more same IDs are present.

In addition, when there is a change in the presence of the chips 120 at least in the game table chip tray 17 and the storage 62, the management control device 50 records time or a place (the storage 62, the game table chip tray 17, or the like) at which the change is present in the database 51 in association with the side ID 126 and, as a result of the search of the database 51, when there is a situation in which two or more same side IDs 126 are present, extracts the side ID 126 and information of time or a place recorded in the database 51 in association with the side ID 126 from the database 51 and stores the side ID and the information that have been extracted, and thus, time at which chip 120 to which the side ID 126 is attached, which has been detected first (used first or cashed), enters/exits the game table chip tray 17 or the storage 13 or a place of the game table chip tray 17 or the storage 13 in which the chips 120 are stored can be specified by using the database 51. When the time and the place can be specified, a suspicious person for the use of unjust chips 120 or the like can be specified from the recorded video of the camera device 2.

In this management system of chip, the management control device 50 can specify the types and the numbers of the chips 120 bet on the bet area 8 of the game table 4 by using the ID reading device 53. The chips 120 of the bet area 8 are imaged by the camera device 2 b that particularly images the bet area 8 and, also for the side ID 126 of the chip 120 present on the bet area 8 of the game table 4, determines the following events by searching the database 51.

1) A side ID 126 that has not been present in the database 51 is newly present in the bet area 16.

2) Two or more same IDs are present.

The management control device 50 has a function of generating an error signal when a situation of 1) or 2) described above is present.

The management control device 50 of this system, the ID reading device 53 disposed inside, and the chip determining device 52 specifying the types and the numbers of chips 120 have a structure integrally including a computer formed as one body or by a plurality of configurations, a program, and a memory.

Next, details of chip 120 (so-called substitute currency for gaming) used in this system will be described. FIG. 17 is a side view of chip 120 used in this system, the chip 120 is formed by stacking a plurality of plate-shaped plastic layers having different colors, forming the plastic layers to be integrated using a means of thermo-compressing or the like, and then, punching holes in the shapes of circles and quadrangles. The chip 120 manufactured in this way has a multi-layer structure in which a coloring layer 121 is included at least in the middle, and white layers 122 or thin-color layers (may be layers of a color thinner than that of the coloring layer 121; not illustrated in the drawing) are stacked on both sides (in FIG. 17, the upper and lower sides) of the coloring layer 121 disposed in the middle. In this way, by employing the multi-layer structure in which the coloring layer 121 is included, and the white layers 122 or the thin-color layers (may be layers of a color thinner than that of the coloring layer 121; not illustrated in the drawing) are stacked on both sides of the coloring layer 121 disposed in the middle, as illustrated in FIG. 17, a stripe pattern (in the stacking direction) when seen from the side face is formed, and, by changing the color (red, green, yellow, blue, or the like) of the coloring layer 121 for each type (10 points, 20 points, 100 points, 1000 points, and the like) of the chip 120, the type of the chip 120 can be specified.

In addition, as illustrated in FIG. 17, in the chip 120, a side ID 126 representing the type of chip 120 is applied to the side faces of the white layers 122.

In the outermost layers, transparent layers 124 are arranged, and each interlayer is thermo-compressed to form a structure of at least five layers. Such chip 120 is formed by using a plastic material having a thin long shape, and layers (at least the coloring layer 121 and the white layers 122) are thermo-compressed to form a closely adhering state (the structure of five layers or the like) in the state of a long length, and thereafter, holes having a circular shape, a rectangular shape, or the like are formed therein through press or the like.

When a hole is formed through the press, die of mold for punching, and the size of punching are designed, and R processing (round angle) is performed for the ends of the transparent layer 124 of the outermost layer.

The transparent layers 124 may be a coat layer of varnish. The side ID 126 is attached to at least three positions on the side face of the chip 120. The side ID 126 is attached through inkjet printing using ink that is visible for visible light.

Particularly, in this embodiment, the side ID 126 is configured to be attached as presence/absence of marks C of a plurality of rows and a plurality of columns. In the marks C of the plurality of rows and the plurality of columns, as illustrated in FIG. 17, upper and lower marks C are paired to configure a code, and a code of ten digits is formed in the case illustrated in FIG. 17. A configuration in which upper and lower marks C are paired to configure a code (four types) is illustrated in FIG. 18. A letter “Y” disposed to the side of marks C is an identification mark used for identifying upper and lower sides of a mark. A code configured by marks C is configured to specify a predetermined combination of marks C. As a result, in the example illustrated in FIG. 18, there are four types of combination of the marks C of upper and lower two columns, and, by printing these in ten columns, four to the power of 10 codes can be configured. Since there are four types of a 10-digit code, 4 to the power of 10 codes are acquired, and accordingly, the side IDs 126 of chip 120 can be sufficiently assigned.

The chip 120 forms a stripe pattern on the side face in the stacking direction by employing a multi-layer structure in which a plurality of plastic layers having different colors are stacked, the coloring layer 121 is included at least in one layer, the white layers 122 or the thin-color layers are stacked on a further outer side than the coloring layer 121 and has a configuration enabling the type of the chip 120 to be specified using the coloring layer 121. The side IDs 126 are disposed at least three positions (preferably, six positions) on the side face of the white layer 122 or the thin-color layer, and, in this example, six side IDs are disposed at a predetermined interval of 60 degrees in the rotation direction (circumferential direction). The side IDs 126 individually identifiable (different for each one) are attached to chip 120, and the side IDs 126 are disposed at a predetermined interval of 60 degrees in the rotation direction (circumferential direction) such that the side ID is necessarily seen from the lateral side. The side IDs 126 attached to the chip 120 are read by the ID reading device 53 described above. The type, the manufacturing information, and the like of chip 120 can be specified by reading the side ID 126 by using the ID reading device 53, and a configuration in which the side ID 126 can be managed in the database 51 is formed. In this embodiment, the side IDs 126 are attached using ink (visible ink) that is visible for visible light through inkjet printing. The side IDs 126 may be printed using at least one or a combination of ink (ink absorbing infrared rays) that is not visible for visible light and ink (including a side ID that is very small and is difficult to see) that is visible for at least visible light. In addition, the side IDs 126 may be printed by combining a plurality of such ink of a plurality of types. The ID reading device 53 includes at least a plurality of cameras (that is, a visible-light camera in a case where ink is visible ink, an infrared-ray camera in a case where ink is infrared reactive ink, and an ultraviolet camera in a case where ink is UV ink (UV radiator and a visible-light camera)) corresponding to the ink used for printing the side ID 126 or includes a camera capable of performing switching among a plurality of functions of cameras (a visible-light camera, an infrared ray camera, and an ultraviolet ray camera (an UV radiator and a visible-light camera or the like)) corresponding to the ink.

In the case illustrated in FIG. 19, in chip 120-1, side IDs 126 are printed using ink (ink absorbing infrared rays) that is not visible for visible light. In chip 120-2, marks C of a plurality of rows and a plurality of columns are printed using ink that is seen dark for visible light. In chip 120-3, additionally, marks C are printed using ink seen dark for visible light also between the side IDs 126, and the side IDs 126 are configured to dissolve in the design not to be visually distinguished. In chip 120-4, a start point and an end point of the side ID 126 are represented by a mark Cf representing the end. When the chips 120-1 to 120-4 are seen using an infrared-ray camera, ink absorbing infrared rays absorbs infrared rays to be seen dark, and the chips 120-1 to 120-4 can be imaged in a state (represented as the chip 120-5) in which the side ID 126 can be read. In addition, the upper and lower sides of the side ID 126 are illustrated using a mark CL representing the upper and lower sides. A relation between the upper and lower sides of the mark is as illustrated in FIG. 17. In addition, the side IDs 126 may be printed using a combination of ink that is visible for visible light and an infrared ray absorption ink.

The side IDs 126 attached to the chip 120 are read by the ID reading device 53 described above, and the ID reading device 53 can read the chip 120 held in the storage 62 of a cashier of a game house and the game table chip tray 17 of the game table, and actually, as illustrated in FIG. 20A, when the chips 120 is stacked horizontally, the side IDs 126 can be read. In addition, the chips 120 stacked in the bet area 8 or the like, as illustrated in FIG. 20B, can be also read.

Furthermore, in the chip 120, a face code using UV ink or ink (carbon black ink) absorbing infrared rays is arranged on the surface (X) of the white layer 122 (see FIG. 9B).

This face code represents authenticity of chip 120, and, when ultraviolet rays (or infrared rays) hit the face code, the face code becomes visible to the eyes and represents authenticity based on a combination of the forms and a number. While the transparent layers (print layers) 124 are thermos-compressed or coated in the outermost layers to cover a print 123 (100 points or the like) used for specifying a game house and a face code disposed on the surface, embossing process or varnish processing is performed for the transparent layers 124, and the chip 120 is prevented from adhering to each other and is caused to slide well. In the chip 120, a circular recess 127 is arranged at the center of each of the upper and lower faces.

According to the recesses 127, the chip 120 is prevented from being adhere to each other, and, by increasing the diameter of the recesses 127, the chip 120 can slide well.

The R processing (R) is performed for the ends of the transparent layers (print layers) 124 of the outermost layers for which a print 123 (100 points or the like) is performed, and, in the punching process of the chip 100, the surfaces of the white layers 122 are prevented from being deformed to appear on the side face. In addition, it is prevented that a sharp end remains in the chip 100 and damages the hands or the other chip 120. The coloring layer 121 may be formed by colored one layer or a plurality of layers. In addition, metal or ceramic used for increasing the weight may be built in a layer included in the layer of the coloring layer 121. More specifically, in the material of the layer included in the layer of the coloring layer 121, for example, metal powders (for example, a metal oxide of one or a plurality of metal oxides of zinc oxide and titanium oxide) may be contained. In addition, a part of the coloring layer 121 is hollowed out, or a space is arranged between the coloring layer 121 and the white layer 122, and an RFID may be built therein. In such a case, as the side ID 126 of the chip 120, a side ID 126 according to a code using the marks C and a side ID using the RFID are used together.

In the chip 120 configured in this way, the types and the numbers of the chips 120 that is held in the game table chip tray 17 and the storage 62 are specified by the chip determining device 52 through the camera device 2 and the ID reading device 53, and the side IDs 126 of the chip 120 present on the game table chip tray 17 and the storage 62 are managed in the database 51 together with the presence information thereof. In this way, at least, it is inspected whether 1) a side ID 126 that has not been present in the database 51 is newly present 2) two or more same side IDs 126 are present. By determining the occurrences of the situations of 1) and 2) described above by searching for all the side IDs 126, the inspection is realized.

As described above, while a game participant 6 can perform exchange of cash 61 for chips in the cashier 60, exchange of cash 61 for chips 120 can be performed also in the game table 4. The camera device 2 images bills placed on the game table 4 to exchange them for chips 120. That is, a plurality of camera devices 2 imaging the chips 120 disposed on the game table 4 are arranged at different positions to have different heights.

The management control device 50 specifies the types and the numbers of chips 120 to be discharged from the chip tray 17 in the exchange from bills by using a result of imaging of bills using the camera device 2. The management control device 50 compares real total amounts of the chips 120 housed in the chip tray 17 before and after the payment and determines whether or not this difference corresponds to the specified types and numbers of the chips 120 to be discharged.

That is, the management control device 50 determines through a comparison whether or not a total amount of the chips 120 perceived in the chip tray 17 corresponds to an increase/decrease according to a paid amount of the chips 120 corresponding to exchanged bills after the exchange of the bills and the chips 120. In addition, when collection and re-payment according to a result of winning/losing of a game are simultaneously performed, the management control device 50 determines through a comparison whether or not the total amount corresponds to an amount of the chips 120 bet by all the players 6 and an increase/decrease in the chips 120 calculated based on a result of the winning/losing of the game.

Here, the management control device 50 is a control device having an artificial intelligence-utilizing or deep-learning structure capable of acquiring information of the types and the numbers of the chips 120 even in a state in which a part or whole one unit of the chips 120 is hidden when the types and the numbers of the chips 120 are measured and determined.

As described above, the side IDs 126 are attached to the white layers 122 or the thin-color layers of the side face of the chip 120 at least at three or more positions spaced apart in a rotation direction (circumferential direction). The types and the manufacturing information of chips 120 can be specified by reading the side IDs 126 by using the ID reading device 53. The specified information specified through measurement has a configuration that can be collated and managed with the database 51.

The management control device 50 may be a control device having an artificial intelligence-utilizing or deep learning structure. The management control device 50 can perceive the position 8 (a position betting on a player, a banker, or a pair), the types (a value of a different amount is assigned to the chip for each color), and the numbers of the chips 120 by using an artificial intelligence-utilizing type computer or control system, a deep-learning (structure) technology, a self-learning function, or the like.

Hereinafter, a modified example of the chip 120 will be described. In the modified example, on the side face of the chip 120, a seven-digit number is printed as the side ID 126. In the example illustrated in FIG. 21, a white layer 122 is disposed in the middle, and, under the white layer, a coloring layer 121 is disposed. A number as a mark is printed on the white layer 122 disposed in the middle and configured a side ID 126. When 10 types of combinations of numbers are printed in seven digits, 10 to the power of 7 codes can be configured, and accordingly, the side IDs 126 of chip 120 can be sufficiently assigned. In the camera device 2 and an image analysis thereof, there are cases where it is difficult to determine and read a number, a combination of marks C described in the previous embodiment is considered to be advantageous in the image analysis.

There is a correct database (not illustrated in the drawing), and the relation among the information is inspected by comparing a reading result with the database. This inspection is used for preventing the occurrence of a defect by detecting a print error in the face code M and the side ID 126 or for discrimination with a fake.

Such technologies are technologies for recognizing a target included in an image by performing image recognition for a captured image, and particularly, in recent years, a target is recognized with high accuracy by using a deep learning technology having multi-layered neural network.

In this deep learning technology, generally, in an intermediate layer between an input layer and an output layer of a neural network, layers overlap each other over a plurality of stages, and accordingly, a target is recognized with high accuracy.

In these deep learning technologies, particularly, a convolutional neural network has attracted attention owing to high performance according to recognition of a target based on conventional image features.

In the convolutional neural network, a recognition target image to which labels are assigned is learned, and main target included in the recognition target image is recognized. In a case where a plurality of main targets are present in a learning image, a designation is made using an area rectangular, and learning is performed with a label assigned to an image corresponding to the designated area. In addition, in the convolutional neural network, a main target in an image and the position of the target can be determined.

The convolutional neural network will be further described. In a target recognition process, by performing an edge extracting process and the like for a recognition target image, candidate areas are extracted based on local features, and, after feature vectors are extracted by inputting the candidate areas to the convolutional neural network, classification is performed, and a candidate area having a classified highest certainty factor is acquired as a result of the recognition.

Here, the certainty factor is an amount representing a relative degree of highness of the similarity of a subject of an image learned together with an image area and a label relative to the similarity of the other classes.

In addition, devices having artificial intelligence-utilizing or deep-learning structures are disclosed in U.S. Pat. No. 9,361,577, US 2016/171336, US 2015/036920, JP 2016-110232, and the like, the content of which is incorporated herein by reference.

FIG. 25 is a plan view of a game table according to the present embodiment. FIG. 26 is a plan view of a chip tray according to the present embodiment. FIG. 27 is a view showing an entire configuration of a management system of chips including the chip tray. In FIGS. 25 to 29, the same components as those of the first to third embodiments are denoted by the same reference numerals, and a detailed description thereof will be omitted.

A game table 4 is a table for a baccarat game, and is provided with a bet area 44 of each of seven players. The bet area 44 of each player includes each area of a player (PLAYER) 441, a banker (BANKER) 442, a tie (TIE) 443, a player pair (P) 444, and a banker pair (B) 445. Each player puts a bet amount of chips on a position corresponding to a target to be bet, thereby making a bet. The game table 4 is further provided with a player card area 45 for putting a drawn player card and a banker card area 46 for putting a drawn banker card.

In front of a dealer position of the game table 4, a chip tray 17 for the dealer to accommodate the chips is provided. At least a part of the chip tray 17 is buried in the game table 4.

Chips 120 used in the present embodiment have the same configuration as that of the chips of the first to third embodiments. That is, the chips 120 have marks, patterns, or colors that can specify their types (values) from each of surfaces and side surfaces thereof. In addition, radio frequency identifications (RFIDs) storing at least information that can specify types of chips 120 are embedded in the chips 120.

A camera device 2 is provided above the game table 4, and photographs the bet area 44. In the game table 4 according to the present embodiment, seven player positions (“1”, “2”, “3”, “5”, “6”, “7”, and “8” in FIG. 25) are provided, such that seven players can participate in a game. The camera device 2 photographs the bet areas 44 of all the player positions. It is not necessary for one camera device 2 to photograph the bet areas 44 of all the player positions, and all the bet areas 44 may be photographed in a shared manner by a plurality of camera devices 2.

A management control device 50 has all the functions described in the first to third embodiments. The management control device 50 specifies positions (bet targets), types, and the numbers of chips put in the bet areas based on an image photographed by the camera device 2. A device including the camera device 2 and the management control device 50 functions as a measuring device or a bet determining device for measuring positions, types, and the numbers of chips on the game table 4, and has the same configuration and function to those of the system including the camera device 2 and the image analyzing device 12 according to the first embodiment.

A card distributing device 3 also has the same configuration and function as those of the card distributing device of the first embodiment. That is, the card distributing device 3 determines a win/loss result of the game on the game table 4 and displays the determined win/loss result of the game on a result display lamp. In addition, the card distributing device 3 transmits the determined win/loss result of the game to the management control device 50. The management control device 50 has a function of grasping the positions, the types, and the numbers of chips on the game table 4 and calculating a balance of a casino side on the game table 4 using the win/loss result obtained from the card distributing device 3 as the win/loss determining device.

The management control device 50 grasps an amount of chips on the game table 4 to be collected and an amount of chips to be paid by the casino side in the game on the basis of a bet content determined based on the image obtained from the camera device 2 and information on the win/loss result obtained from the card distributing device 3, and compares the amount to be collected and the amount to be paid with an amount of chips actually increased in the chip tray 17 due to collection and an amount of chips actually decreased in the chip tray 17 due to payment, respectively.

In addition, the management control device 50 reads the RFIDs of the chips 120 accommodated in the chip tray 17 at predetermined time intervals, and stores information of the read RFIDs when a change occurs. The management control device 50 compares types and the numbers of chips at the past point in time with types and the numbers of chips at the present point in time based on the stored information, and calculates an increase/decrease amount of chips 120 in the chip tray 17.

As shown in FIG. 26, the chip tray 17 includes an accommodating portion 170 and display lamps 173 to 176. The accommodating portion 170 includes a plurality of columns, and each column has a configuration in which chips can be stacked and accommodated in a thickness direction. As shown in FIG. 27, an antenna 177 is disposed below the accommodating portion 170.

The display lamp 173 displays whether or not a balance between a collected amount and a paid amount is correct. The display lamp 174 displays whether or not a total amount of the collected amount is correct and whether or not a total amount of the paid amount is correct. The display lamp 175 displays whether or not a collection amount or a payment amount for chips bet on the pair is correct.

The display lamps 176 have a total of seven display lamps corresponding to the seven player positions. In the display lamp 177, in a collection step, display lamps corresponding to players (players losing the game) from which chips are to be collected are turned on, and in a payment step, display lamps corresponding to players (players winning the game) to which chips are to be paid are turned on. In FIG. 27, only the display lamp 173 is shown as a representative of the display lamps 173 to 176, and the other display lamps 174 to 176 are not shown.

The management control device 50 controls turn-on and turn-off of the display lamps 173 to 176 in order to display a result (consistency or inconsistency) of the comparison. The management system of chips according to the present embodiment grasps whether or not liquidation of the chips was correctly performed, in real time, using the display lamps 173 to 176. The management system of chips according to the present embodiment grasps whether or not a fraudulent chip is included in the collected chips, in real time.

The management control device 50 first specifies players that are participating in the game on the game table 4, and associates the players that are participating in the game with player position numbers (“1”, “2”, “3”, “5”, “6”, “7”, and “8”) of the game table 4. Specifically, the management control device 50 can specify a player of each player position using a face authentication system or a members card.

When the game ends, the management control device 50 grasps chips (winning chips of the casino side) to be collected by the dealer for each player based on a game result, and turns on the display lamps 176 corresponding to player positions at which the chips are to be collected. Therefore, the dealer can grasp at which player position the chips are to be collected.

When the game ends, the dealer first collects all the chips to be collected from bet areas of players losing the game (collection step), and then pays chips to players winning the game (payment step). In the collection step, the dealer accommodates the chips collected from the bet areas of the game table 4 in the accommodating portion 170 of the chip tray 17 depending on the display lamps 176. Specifically, the dealer accommodates the collected chips in any one of two right columns, which are a collecting portion, in order of the player position numbers.

The management control device 50 determines that the chips are collected from the bet area 44 and an amount of collected chips based on the image obtained from the camera device 2 whenever the dealer collects chips from the bet area 44 and accommodates the collected chips in the collecting portion of the accommodating portion 170, and determines an amount (increase amount) of chips accommodated in the collecting portion based on a radio wave received by the antenna 177. The two right columns of fourteen columns as the accommodating portion 170 are used as the collecting portion in the present embodiment, but the collecting portion that accommodates the collected chips may be, for example, the transverse collection chip tray 171 shown in FIG. 13A or the collection chip tray 171 provided to be spaced apart from other columns, as shown in FIG. 13B.

Here, the management control device 50 calculates the increase amount by calculating a difference between total amounts of chips in the accommodating portion 170 before and after the collection using the RFIDs for each player. As described above, the management control device 50 reading information on types (values) of chips from the RFIDs of the chips held in the accommodating portion 170 to determine an amount of chips held in the accommodating portion 170 corresponds to a dealer chip determining device of the present invention.

The management control device 50 further determines whether or not an actual collection amount (image collection amount) determined based on the image obtained from the camera device 2, an increase amount (RFID collection amount) of chips in the collecting portion determined based on the radio wave received by the antenna 177, and a collection amount (calculated collection amount) calculated based on a game result and bet contents of the players losing the game are consistent with one another.

When all of the image collection amount, the RFID collection amount, and the calculated collection amount are consistent with one another, the management control device 50 turns off the corresponding display lamp 176. The dealer can confirm that the collection of the chips from the player has been accurately completed by confirming the turn-off of the display lamp 176.

On the other hand, when the image collection amount, the RFID collection amount, and the calculated collection amount are inconsistent with one another, the display lamp 176 is in a state in which it is turned on. Therefore, the dealer can know that the collection of the chips from the corresponding player has not been accurately completed or that there was the fraudulent chip in the collected chips.

When the collection of the chips as described above is completed for all the players losing the game, all the display lamps 176 are turned off. At this point in time, the management control device 50 again determines a total increase amount in the collecting portion by the RFIDs, compares the total increase amount with a total calculated collection amount calculated based on the game result and bet contents of all the players losing the game, and turns on the display lamp 174 when the total increase amount and the total calculated collection amount are consistent with each other.

Here, the management control device 50 calculates a total RFID collection amount by calculating a difference between the total amount of chips in the accommodating portion 170 calculated by the RFIDs before the start of the collection step after an end of the game and the total amount of chips in the accommodating portion 170 calculated by the RFIDs after completion of the collection. The dealer can grasp that the collection of the chips has been accurately completed by confirming that the display lamp 174 is turned on.

The management control device 50 determines whether or not all of the image collection amount determined based on the image obtained from the camera device 2, the RFID collection amount determined based on the radio wave received by the antenna 177, and the calculated collection amount calculated based on the game result and the bet contents of the players losing the game are consistent with one another in the above description, but the management control device 50 may also determine only whether or not the image collection amount and the calculated collection amount are consistent with each other or may determine only whether or not the RFID collection amount and the calculated collection amount are consistent with each other.

In addition, in the above description, the management control device 50 again determines the total increase amount by the RFIDs when it is determined that the collection of the chips has been completed for all the players losing the game, and turns on the display lamp 174 when the total increase amount is consistent with the total calculated collection amount. Instead of this, the management control device 50 may operate as follows. That is, the management control device 50 stores the read information of the RFIDs whenever there is a change in the chips 120 in the chip tray 17 as described above, but at the same time, the management control device 50 may determine the total increase amount whenever there is the change in the chips 120 in the chip tray 17, determine whether or not the total increase amount is consistent with the total calculated collection amount, and turn on the display lamp 174 at a point in time in which it is determined that the total increase amount is consistent with the total calculated collection amount.

Next, the dealer pays the chips to the players winning the game (payment step). When the collection of the chips from all the players losing the game is completed, the management control device 50 turns on the display lamps 176 corresponding to the players to which the chips are to be paid. The dealer can confirm the players to which the chips are to be paid by confirming the display lamps 176. In the payment step, the dealer takes out chips corresponding to a payment amount from the accommodating portion 170, and puts the taken-out chips in the bet areas of the corresponding players, thereby performing payment.

The management control device 50 determines that the chips are paid to the bet area 44 and an amount of paid chips based on the image obtained from the camera device 2 whenever the dealer takes out chips from the accommodating portion 170 and puts the taken-out chips on the game table 4, and determines an amount (decrease amount) of chips taken out from the accommodating portion 170 based on the radio wave received by the antenna 177. Here, the management control device 50 calculates the decrease amount by calculating a difference between total amounts of chips in the accommodating portion 170 before and after the payment, using the RFIDs, for each player.

The management control device 50 further determines whether or not an actual payment amount (image payment amount) determined based on the image obtained from the camera device 2, a decrease amount (RFID payment amount) of chips in the accommodating portion 170 determined based on the radio wave received by the antenna 177, and a payment amount (calculated payment amount) to the players winning the game, calculated based on a game result and bet contents are consistent with one another.

When all of the image payment amount, the RFID payment amount, and the calculated payment amount are consistent with one another, the management control device 50 turns off the corresponding display lamp 176. The dealer can confirm that the payment of the chips to the player has been accurately completed by confirming the turn-off of the display lamp 176.

On the other hand, when all of the image payment amount, the RFID payment amount, and the calculated payment amount are inconsistent with one another, the display lamp 176 is in a state in which it is turned on. Therefore, the dealer can know that the payment of the chips to the corresponding player has not been completed.

When the payment of the chips is completed for all the players winning the game, all the display lamps 176 are turned off. At this point in time, the management control device 50 again determines a total decrease amount in the accommodating portion 170 by the RFIDs, compares the total decrease amount with a total calculated payment amount calculated based on the game result and the bet contents, and turns on the display lamp 174 when the total decrease amount and the total calculated payment amount are consistent with each other.

Here, the management control device 50 calculates a total RFID payment amount by calculating a difference between the total amount of chips in the accommodating portion 170 calculated by the RFIDs before the start of the payment step after completion of the collection and the total amount of chips in the accommodating portion 170 calculated by the RFIDs after completion of the payment. The dealer can grasp that the payment of the chips has been accurately completed by confirming that the display lamp 174 is turned on.

The management control device 50 determines whether or not all of the image payment amount determined based on the image obtained from the camera device 2, the RFID payment amount determined based on the radio wave received by the antenna 177, and the calculated payment amount calculated based on the game result and the bet contents of the players winning the game are consistent with one another in the above description, but the management control device 50 may also determine only whether or not the image payment amount and the calculated payment amount are consistent with each other or may determine only whether or not the RFID payment amount and the calculated payment amount are consistent with each other.

In addition, in the above description, the management control device 50 again determines the total decrease amount by the RFIDs when it is determined that the payment of the chips has been completed for all the players winning the game, and turns on the display lamp 174 when the total decrease amount is consistent with the total calculated payment amount. Instead of this, the management control device 50 may operate as follows. That is, the management control device 50 stores the read information of the RFIDs whenever there is a change in the chips 120 in the chip tray 17 as described above, but at the same time, the management control device 50 may determine the total decrease amount whenever there is the change in the chips 120 in the chip tray 17, determine whether or not the total decrease amount is consistent with the total calculated payment amount, and turn on the display lamp 174 at a point in time in which it is determined that the total decrease amount is consistent with the total calculated payment amount.

When the liquidation (collection and payment) of the chips is completed as described above, the management control device 50 determines whether or not the total increase/decrease amount of chips in the accommodating portion 170 due to the liquidation is correct. In detail, the management control device 50 calculates a total increase/decrease amount (total RFID increase/decrease amount) due to the liquidation by calculating a difference between the total amount of chips in the accommodating portion 170 calculated by the RFIDs before the start of the liquidation after the end of the game and the total amount of chips in the accommodating portion 170 calculated by the RFIDs after an end of the liquidation.

Meanwhile, the management control device 50 calculates a total increase/decrease amount (total calculated increase/decrease amount) of the dealer due to the liquidation of the game based on the game result and the bet contents. The calculated increase/decrease amount can be calculated by subtracting the total calculated payment amount from the calculated collection amount. The management control device 50 compares the total RFID increase/decrease amount with the total calculated increase/decrease amount, and turns on the display lamp 174 when the total RFID increase/decrease amount and the total calculated increase/decrease amount are consistent with each other. The dealer can confirm that the liquidation of the chips in the game has been accurately completed and can start the next game, by confirming that the display lamp 174 is turned on.

Next, the display lamp 175 will be described. The display lamp 175 functions as a pair lamp. In the baccarat game, the player can also make a bet on “pair” in addition to “player”, “banker”, and “tie”. The “pair” is to make a bet on the fact that ranks of first distributed two cards are consistent with each other. Specifically, the “pair” includes “player pair” making a bet on consistency between ranks of two player cards and “bank pair” making a bet on consistency between ranks of two banker cards.

When any one of the players makes a bet on the pair and two ranks are consistent with each other (the pair is established), a predetermined multiple (for example, 11 times) of a bet amount is paid to a player making a bet on the pair regardless of a game result (“player”, “banker”, or “tie”). When the pair is not established, all the chips bet on the pair are collected. When the pair is not established at a point in time in which first four cards (two player cards and two banker cards) are drawn, chips bet on the pair at that point in time are collected.

When a bet is made on the pair, the management control device 50 calculates a total calculated collection amount (when the pair is not established) or a total calculated payment amount (when the pair is established) at the point in time in which the four cards are drawn, and compares the total calculated collection amount or the total calculated payment amount with a total increase/decrease amount of chips in the accommodating portion 170 calculated using the RFIDs before and after liquidation of the pair. It is to be noted that the management control device 50 can recognize whether or not chips are bet on the pair and an amount of bet chips, based on the image obtained from the camera device 2.

The management control device 50 turns on the display lamp 175 when the total calculated collection amount or the total calculated payment amount is consistent with the total increase/decrease amount of chips in the accommodating portion 170. The dealer can confirm that the liquidation of the pair has been accurately completed by confirming the turn-on of the display lamp 175.

Instead of the above, the management control device 50 may also turn on the display lamp 175 when the chips are bet on the pair. A timing in which the display lamp 175 is turned on may be a timing in which the bet is closed or a timing in which four cards are drawn. In this case, the dealer can recognize that it is necessary to perform the liquidation of the pair by confirming that the display lamp 175 is turned on.

In addition, in this case, the management control device 50 turns off the display lamp 175 when the total calculated collection amount or the total calculated payment amount is consistent with the total increase/decrease amount of chips in the accommodating portion 170. The dealer can confirm that the liquidation of the pair has been accurately completed by confirming the turn-off of the display lamp 175.

In the baccarat game, there are a case where the game ends by the draw of four cards (two player cards and two banker cards) depending on ranks of distributed cards and a case where a fifth card or the following sixth card is drawn. In the case where the game ends by the draw of the four cards, as soon as the liquidation of the pair ends, the general liquidation described above is performed. In the case where the fifth card or a following card is drawn, the liquidation of the pair is performed after a fourth card is drawn, the fifth card (or the following sixth card) is drawn when the liquidation of the pair is completed, and the general liquidation described above is performed when the game ends.

The display lamps 176 of the players losing the game from which the chips are to be collected are turned on and are turned off in order of the players from which the collection is completed in the collection step and the display lamps 176 of the players winning the game to which the chips are to be paid are turned on and are turned off in order of the players to which the payment is completed in the payment step in the abovementioned embodiment, but all the display lamps 176 may also be turned on with colors distinguished between the players winning the game and the players losing the game at a point in time in which the game ends.

For example, the display lamps 176 corresponding to the players losing the game may be turned on with a red color, and the display lamps 176 corresponding to the players winning the game may be turned on with a green color. In this case, it can be confirmed that the collection of the chips from all the players losing the game has been accurately completed by confirming that all the red display lamps 176 are turned off, and it can be confirmed that the payment of the chips to all the players winning the game has been accurately completed by confirming that all the green display lamps 176 are turned off.

FIG. 28 is a plan view of a chip tray according to a modified example. In a chip tray 17 of FIG. 28, the same components as those of the chip tray 17 of FIG. 26 are denoted by the same reference numerals, and a description thereof will be appropriately omitted. In the chip tray 17 according to the present modified example, display lamps 1761 to 1765 for each bet target (specifically, a display lamp 1761 displaying “player”, a display lamp 1762 displaying “banker”, a display lamp 1763 displaying “tie”, a display lamp 1764 displaying “player pair”, and a display lamp 1765 displaying “banker pair”) and a display lamp 178 displaying that liquidation has been accurately completed are provided for each player position.

The display lamps 1761 to 1765 are turned on corresponding to bet targets (positions at which chips are put) of players, respectively, and turned off when liquidation is completed. The display lamp 178 is turned on when liquidation is accurately completed for each player.

The chip tray 17 according to the present modified example further includes display lamps 1741 to 1745 displaying that the liquidation has been accurately completed for each of the bet targets (“player”, “banker”, “tie”, “player pair”, and “banker pair”). Depending on a win/loss result of the game, any one of the “player”, the “banker”, and the “tie” becomes payment and the others become collection. In addition, when the player pair is established, the “player pair” becomes payment, and when the player pair is not established, the “player pair” becomes collection. Similarly, when the banker pair is established, the “banker pair” becomes payment, and when the banker pair is not established, the “banker pair” becomes collection. The display lamps 1741 to 1745 are turned on when liquidation (collection or payment) for each of the “player”, the “banker”, the “tie”, the “player pair”, and the “banker pair” is accurately completed.

FIG. 29 is a plan view of a chip tray 17 according to another modified example. As in the example of FIG. 29, only a display lamp 173 displaying whether or not a balance between a collected amount and a paid amount is correct may be provided in the chip tray 17.

FIG. 30 is a plan view of a chip tray 17 according to still another modified example. As shown in FIG. 30, only a display lamp 173 displaying whether or not a balance between a collected amount and a paid amount is correct and a display lamp 174 displaying whether or not a total amount of the collected amount is correct and whether or not a total amount of the paid amount is correct may be provided in the chip tray 17.

The management control device 50 determines an amount of chips accommodated in the chip tray 17 by wirelessly reading the RFIDs using the RFIDs embedded in the chips and the antenna 177 embedded below the chip tray 17 in the abovementioned embodiment and the modified examples thereof, but an amount of chips accommodated in the chip tray 17 may also be determined by providing a camera device photographing chips accommodated in the chip tray 17 and performing image recognition on an image obtained from the camera device. In this case, the RFIDs may not be embedded in the chips.

In addition, an example in which a plurality of display lamps including the display lamp 173 are configured as physically realized lamps has been described in the abovementioned embodiment, but these lamps may be configured as images on a display device such as a liquid crystal panel.

In addition, in the abovementioned embodiment, the information on the types and the numbers of chips 120 accommodated in the chip tray 17 is determined by reading the RFIDs embedded in the chips 120. Instead of or in addition to this, the information on the types and the numbers of chips 120 accommodated in the chip tray 17 may be determined by providing a camera device photographing the chips 120 accommodated in the chip tray 17 and performing image recognition in the management control device 50. In this case, the camera device photographing the chips 120 accommodated in the chip tray 17 may be used as the camera device 2 described above or may be provided as a dedicated camera device.

In addition, when the image recognition is performed on the image obtained from the camera device in addition to the reading of the RFIDs, verification of the chips 120 may be performed by comparing the number of chips 120 obtained by the reading of the RFIDs with the number of chips determined by the image recognition. When the RFIDs are damaged in the chip tray 17 or a chip (fraudulent chip) that does not have the RFID is accommodated in the chip tray 17, the number of chips determined by the image recognition becomes larger than the number of chips determined by the reading of the RFID. Therefore, when such inconsistency occurs, the management control device 50 turns on the display lamp, such that the dealer can grasp that the fraudulent chip is included in the chip tray 17 through the display lamp.

In particular, by performing the reading of the RFIDs and the image recognition at predetermined time intervals to perform the comparison whenever the information is updated, when the inconsistency between the number of chips determined by the reading of the RFIDs and the number of chips determined by the image recognition occurs, it is seen that the inconsistency is due to chips 120 recently added to the chip tray 17, such that it is also possible to specify a player who had the fraudulent chip.

In addition, the management control device 50 may verify that chips do not exist on the game table as a result of collecting the corresponding chips from the game table by the dealer. In this case, specifically, the management control device 50 verifies that chips 120 corresponding to a calculated collection amount do not exist on the game table 4 based on the image obtained from the camera device 2 by determining on which bet target which type of and how many chips are bet based on the image obtained from the camera device 2 and further determining an amount (calculated collection amount) to be collected according to a game rule based on a game result in the card distributing device 3.

Further, the management control device 50 may verify that the collection has been accurately performed by comparing an amount (image collection amount) of chips that do not exist on the game table 4 with an amount of chips added to the chip tray 17 based on the image obtained from the camera device 2. In this case, the management control device 50 turns on the display lamp when the image collection amount and the amount of chips added to the chip tray 17 are inconsistent with each other as a result of the comparison.

In addition, the management control device 50 may verify that chips exist on the game table as a result of paying the corresponding chips to the game table by the dealer. In this case, specifically, the management control device 50 verifies that chips 120 corresponding to a calculated payment amount are added onto the game table 4 based on the image obtained from the camera device 2 by determining on which bet target which type of and how many chips are bet based on the image obtained from the camera device 2 and further determining an amount (calculated payment amount) to be paid according to a game rule based on a game result in the card distributing device 3.

Further, the management control device 50 may verify that the payment has been accurately performed by comparing an amount (image payment amount) of chips added onto the game table 4 with an amount of chips taken out from the chip tray 17 based on the image obtained from the camera device 2. In this case, the management control device 50 turns on the display lamp when the image payment amount and the amount of chips taken out from the chip tray 17 are inconsistent with each other as a result of the comparison.

As described above, the dealer basically collects the chips 120 bet by the players losing the game in order of player position numbers. The management control device 50 determines whether or not the dealer takes the chips in order according to this rule (in order of the player position numbers), and further determines whether or not an amount of chips that are sequentially collected is correct. In this case, the management control device 50 determines how far chips have been collected (up to which player position number chips have been collected), in addition to individual player positions and all player positions, and determines whether or not the chips 120 collected from the game table 4 have been certainly added to the chip tray 17 in each step depending on the determination. For example, when chips 120 of three places are collected, the management control device 50 determines whether or not the chips 120 of the three places have been certainly accommodated in the chip tray 17.

As described above, according to the present embodiment and the modified examples thereof, the display lamp 173 and the like for displaying that the increase/decrease in the chips in the chip tray 17 after the end of the game is accurate and/or inaccurate is provided, and it is thus possible to confirm whether or not the liquidation has been accurately performed, in real time at the time of performing the liquidation.

While various embodiments of the present invention have been described hereinabove, the abovementioned embodiments can be modified by those skilled in the art within the scope of the present invention, and devices according to the present embodiment may be appropriately modified as necessary in a game to which they are applied.

The present embodiment relates to a management system that manages a game played using chips in a game house.

The present embodiment corresponds to an application of the fourth embodiment, and the configuration of the management system described in the fourth embodiment can be adopted. In addition, as described above, since the first to third embodiments can be applied to the management system according to the fourth embodiment, the first to third embodiments can also be applied to in the present embodiment.

In the fourth embodiment, when the increase/decrease amount of chips in the chip tray 17 after the end of the game is inconsistent with an ideal increase/decrease amount calculated by calculation, it is possible to inform the dealer that the increase/decrease amount of chips in the chip tray 17 after the end of the game is inconsistent with the ideal increase/decrease amount by turning on the display lamp provided in the chip tray 17. When the dealer recognizes that the inconsistency exists through the display lamp, the dealer can interrupt the game and find a cause of fraud, thereby correcting the fraud or taking an action so that the fraud does not continue.

However, in the case where an amount of inconsistency is small, when the dealer interrupts the game whenever such a small amount of inconsistency occurs, a decrease amount of sales of a casino side due to the interruption of the game becomes larger than loss of the casino side due to the fraud that can be prevented by the interruption of the game.

Therefore, in the present embodiment, when an actual increase amount, decrease amount, or increase/decrease amount (actual liquidation amount) of chips in liquidation after the end of the game and a calculated increase amount, decrease amount, or increase/decrease amount (calculated liquidation amount) are inconsistent with each other, it is determined whether or not a loss amount due to the inconsistency is large, and it is possible to interrupt the game and take an action such as finding of the cause when the loss amount is large.

In the management system according to the present embodiment, the first to third configurations are adopted in the management system including the game table and the chips, and the configuration according to the fourth embodiment is adopted in the chip tray.

A repeated detailed description of each component is avoided, but components necessary for the management system according to the present embodiment are summarized as follows. The management system is configured as the fraud detection system according to the first embodiment, and includes chips, a game table 4, a card distributing device 3 as a win/loss determining device or a game determining unit, a measuring device 19, a chip tray 17, and a management control device 50. The management control device 50 functions as a dealer chip determining device.

The chips can be the chips described in the second or third embodiment, and can be individually identified by colors or marks of surfaces and side surfaces thereof or RFIDs embedded therein. On the game table 4, a game using the chips is played. On the game table 4, bet targets are divided depending on positions, and players put the chips in the corresponding division to bet the chips. The card distributing device 3 grasps which rank and suit of cards have been distributed to the game table 4 by reading contents of discharged cards, and determines a win/loss result of the game by applying information of the distributed cards to a game rule. The win/loss determining device or the game determining unit may be configured to include a camera device 2 that photographs cards on the game table 4 and an image analyzing device 12 that analyzes an image obtained from the camera device 2 to determine win/loss of the game.

The chip tray 17 is a tray for a dealer to hold the chips used on the game table 4, and is installed in the vicinity of a dealer position on the game table 4. In the present embodiment, a tray provided with various display lamps is used as the chip tray 17. The measuring device 19 is configured to include a camera device 2 that photographs the chips on the game table 4 and an image analyzing device 12 that specifies positions, types, and the numbers of chips on the game table 4 by analyzing the image obtained by the camera device 2. It is possible to determine on which bet target on the game table 4 how many chips are bet, by the measuring device 19, and the measuring device 19 becomes a bet determining unit.

The dealer chip determining device is configured to include a camera device 2 that photographs the chips accommodated in the chip tray 17 and an image analyzing device 12 that specifies types and the numbers of chips accommodated in the chip tray 17 by analyzing the image obtained from the camera device 2. In the management system, an actual liquidation amount of chips delivered between the dealer and the player is determined using the measuring device 19 or the dealer chip determining unit to constitute a liquidation determining unit. The management control device 50 performs the following controls based on information obtained from the measuring device, the dealer chip determining device, and the win/loss determining device or based on information obtained from the game determining unit, the bet determining unit, and the liquidation determining unit.

In the present embodiment, the management control device 50 determines whether or not the actual liquidation amount of chips is consistent with the calculated liquidation amount when the game ends and controls display lamps 173 to 176 and the like, depending on a determination result as in the fourth embodiment, but performs a first control by continuously transmitting signals to the display lamps 173 to 176 and the like, without stopping the game when the following conditions are not satisfied and performs a second control by transmitting signals for stopping the game to the display lamps 173 to 176 and the like, when the following conditions are satisfied, in the case where it is determined that the actual liquidation amount and the calculated liquidation amount are inconsistent with each other.

The conditions are as follows: (1) A difference (degree of inconsistency) between an actual liquidation amount and a calculated liquidation amount in a one-time game is larger than a first threshold value (for example, 500 dollars); (2) The total sum of differences (degrees of inconsistency) between actual liquidation amounts and calculated liquidation amounts in recent predetermined-time (for example, five-time) games is larger than a second threshold value (for example, 500 dollars); and (3) A difference (degree of inconsistency) between an actual liquidation amount and a calculated liquidation amount is continuously equal to or larger than a third threshold value (for example, 50 dollars) in recent predetermined-time (for example, three-time) games.

When there is a difference between the actual liquidation amount and the calculated liquidation amount, the management control device 50 performs the second control on the display lamps 173 to 176 and the like, in the case where any one of the above conditions (1) to (3) is satisfied, and performs the first control in other cases.

It is possible to determine an amount (image collection amount) collected from the game table and an amount (image payment amount) paid to the game table as the actual liquidation amount based on the image obtained from the camera device 2 (The image collection amount and the image payment amount are collectively referred to as an “image liquidation amount”.), and it is possible to determine an amount (RFID collection amount) collected in a collecting portion of the chip tray 17 and an amount (RFID payment amount) paid from an accommodating portion 170 of the chip tray 17 as the actual liquidation amount based on a radio wave received by an antenna 177 (The RFID collection amount and the RFID payment amount are collectively referred to as an “RFID liquidation amount”.).

That is, the management control device 50 may compare the image liquidation amount with the calculated liquidation amount, compare the RFID liquidation amount with the calculated liquidation amount, or compare each of the image liquidation amount and the RFID liquidation amount with the calculated liquidation amount in order to compare the actual liquidation amount with the calculated liquidation amount.

When the chip tray 17 shown in FIG. 26 is used as the chip tray, the management control device 50 controls the display lamp as follows. It should be noted that the display lamp is one form of a lighting device and the lighting device is one form of a display device. The management control device 50 turns on the display lamp 173 with a red color as the second control when the difference between the actual liquidation amount and the calculated liquidation amount satisfies any one of the conditions (1) to (3), turns on the display lamp 173 with a yellow color as the first control when the difference between the actual liquidation amount and the calculated liquidation amount does not satisfy any of the conditions (1) to (3), and turns on the display lamp 173 with a green color as a third control when there is no difference between the actual liquidation amount and the calculated liquidation amount, with respect to a balance between the collected amount and the paid amount (liquidation amount), that is, a final balance (that may be minus) obtained by summing up all collections and all payments.

Note that the display lamp 173 is configured to include light emitting diodes (LEDs) of three primary colors, and can express an arbitrary color. The management control device 50 realizes light emission of colors such as the red color, the yellow color, and the green color as described above by controlling emission intensity of each of the LEDs of the three primary colors in the display lamp 173.

The management control device 50 turns on the display lamp 174 with a red color as the second control when a difference between an actual collection amount and a calculated collection amount or a difference between an actual payment amount and a calculated payment amount satisfies any one of the conditions (1) to (3), turns on the display lamp 174 with a yellow color as the first control when the difference between the actual collection amount and the calculated collection amount or the difference between the actual payment amount and the calculated payment amount does not satisfy any of the conditions (1) to (3), and turns on the display lamp 174 with a green color as a third control when there is no difference between the actual collection amount and the calculated collection amount or difference between the actual payment amount and the calculated payment amount.

The display lamps 176 have a total of seven display lamps corresponding to the seven player positions. The management control device 50 turns on display lamps 176 corresponding to players (players losing the game) from which chips are to be collected with a white color in a collection step, and turns on display lamps 176 corresponding to players (player winning the game) to which chips are to be paid with a white color in a payment step.

The management control device 50 determines whether or not a difference between an actual collection amount and a calculated collection amount satisfies any one of the conditions (1) to (3) or whether there is no difference between the actual collection amount and the calculated collection amount, turns off the corresponding display lamp 176 in the case where there is no difference, changes a color of the display lamp 176 from a white color to a red color as the second control when the difference satisfies any one of the conditions (1) to (3) in the case where there is a difference, and changes a color of the display lamp 176 to a yellow color as the second control when the difference does not satisfy any one of the conditions (1) to (3) in the case where there is a difference, for each player in the collection step. Likewise, the management control device 50 determines whether or not a difference between an actual payment amount and a calculated payment amount satisfies any one of the conditions (1) to (3) or whether there is no difference between the actual payment amount and the calculated payment amount, turns off the corresponding display lamp 176 in the case where there is no difference, changes a color of the display lamp 176 from a white color to a red color as the second control when the difference satisfies any one of the conditions (1) to (3) in the case where there is a difference, and changes a color of the display lamp 176 to a yellow color as the second control when the difference does not satisfy any one of the conditions (1) to (3) in the case where there is a difference, for each player in the payment step.

By the control of the display lamp 176 by the management control device 50, the dealer can determine whether there is a small amount of fraud, there is a large amount of fraud, or there is no fraud, for each player.

Likewise, with respect to the display lamp 175, the management control device 50 determines whether a difference between a collection amount or a payment amount and a calculated collection amount or a calculated payment amount for chips bet on “pair” satisfies any one of the conditions (1) to (3) or whether there is no difference, turns on the display lamp 175 with a green color as a third control in the case where there is no difference, turns on the display lamp 175 with a yellow color as the first control in the case where the difference does not satisfy any of the conditions (1) to (3), and turns on the display lamp 175 with a red color as the second control in the case where the difference satisfies any one of the conditions (1) to (3).

Even in the case where the chip tray of FIG. 28 or 29 is adopted as the chip tray 17, various display lamps are turned on with different colors depending on whether or not there is a difference and whether or not the difference satisfies the conditions (1) to (3), as described above. In particular, when the present embodiment is applied to the chip tray 17 of FIG. 28, a display that can specify a player position or a player (game participant) that is a cause of the difference is made.

By the control by the management control device 50, the dealer can interrupt the game and investigate the fraud when the display lamp is turned on with a color corresponding to the second control (when the difference is large) and can continue the game while paying attention to the fraud when the display lamp is turned on with a color corresponding to the first control (when the difference is small), by confirming the colors of the various display lamps. Alternatively, the dealer can take an action so as to solve the difference at that place by performing simple investigation or confirmation within a range that does not hinder the progress of the game when the display lamp is turned on with a color corresponding to the first control. In addition, the present embodiment is also useful even in the case where accuracy of recognition of the chips in the image analyzing device 12, identification of the cards distributed by the card distributing device 3, detection of the chips by the RFIDs and the like, is low. That is, when the accuracy of the recognition of the chips in the image analyzing device 12, the identification of the cards distributed by the card distributing device 3, the detection of the chips by the RFIDs and the like, is low, an inaccurate result such as inconsistency (there is a difference) may be obtained even though amounts are originally consistent with each other (there is no difference), but when an amount of inaccurate result is small, it is possible to ignore the inaccurate result as described above and proceed with the game.

The management control device 50 includes a storage device to record all actual liquidation amounts and calculated liquidation amounts and also store determination result such as determination for at which display lamp which color is displayed, that is, whether there was a difference, whether a signal for stopping the game has been output due to the difference, and whether a signal for continuing the game has been output even though there is a difference. The dealer can grasp the fraud in real time by confirming the various display lamps provided in the chip tray 17, as described above, and a casino operator can grasp the fraud later by confirming data recorded in the storage device.

The management control device 50 can receive an input operation of a user (typically, a casino operator), and change various concrete values of the above conditions based on the input. That is, various parameters of the above conditions are variable.

The conditions (1) to (3) have been set as conditions for determining whether to perform the first control or the second control when there is a difference between the actual liquidation amount and the calculated liquidation amount in the abovementioned embodiment, but all of these conditions (1) to (3) are conditions relating to the difference. The management control device 50 may determine whether to perform the first control or the second control using other conditions, in addition to these conditions or instead of these conditions. For example, in the case where there is a difference between the actual liquidation amount and the calculated liquidation amount, the second control may be performed when a bet amount is equal to or larger than a fourth threshold value, and the first control may be performed when the bet amount is smaller than the fourth threshold value. In addition, the management control device 50 may output a signal for stopping the game by performing the second control when a ratio of an amount of inconsistency to the bet amount is larger than a predetermined ratio (predetermined threshold value) and continuously output a signal without stopping the game by performing the first control when the ratio of the amount of inconsistency to the bet amount is equal to or smaller than the predetermined ratio (predetermined threshold value), in the case where there is a difference between the actual liquidation amount and the calculated liquidation amount.

The lighting device (display lamp) is used as the display device and the management control device 50 performs a control to select the color with which the lighting device is turned on as the first to third controls in the abovementioned embodiment, but a control target of the first to third controls is not limited thereto. For example, in the case where a display panel including a two-dimensional array such as a liquid crystal panel is provided as a display device at the chip tray 17 or other places, whether or not there is a difference and whether or not the difference satisfies any one of the conditions (1) to (3) when there is a difference may be displayed as text information or image information on the display panel. Further, the management control device 50 may display whether the difference satisfies any one of the conditions (1) to (3), on the display panel.

Alternatively, the management control device 50 may control the card distributing device 3. In this case, the card distributing device 3 has a stopper restricting the discharge of the card, and the management control device 50 may operate the stopper at a timing at which the game ends to prohibit the discharge of the card, release the stopper as the first control and the third control to permit the discharge of the card, and operate the stopper as the second control so as to maintain prohibition of the discharge of the card. Alternatively, a control target of the management control device 50 may be an output device that appeals to other senses of a person (dealer), such as a sound output device or a vibration output device.

In addition, the management control device 50 determines whether to perform the first control or the second control based on the conditions (1) to (3) relating to the difference in the abovementioned embodiment, but these conditions (1) to (3) may be applied only when the casino side suffers a loss. For example, only when the difference in a one-time game exceeds the first threshold value but the loss on the casino side occurs due to the difference, it may be determined that the condition of (1) is satisfied, and when the difference causes a loss of the player, it may be determined that the condition is not satisfied.

In addition, the management system evaluates the difference between the actual liquidation amount and the calculated liquidation amount with respect to each of the collection and payment or with the balance by the collection and the payment in the abovementioned embodiment, but the management system may perform a control by evaluating only a difference of any one of the collection and the payment.

In addition, the management control device 50 evaluates the difference between the actual liquidation amount and the calculated liquidation amount and outputs each of a signal indicating that an amount of inconsistency is small and a signal indicating that an amount of inconsistency is large in the abovementioned embodiment, but the management control device 50 may output a signal indicating an amount of inconsistency when there is a difference between the actual liquidation amount and the calculated liquidation amount. In this case, the display device may receive a signal indicating the amount of inconsistency and display the amount of inconsistency (difference amount). The dealer may determine whether to stop or continue the game by viewing the amount of inconsistency displayed on the display device.

In addition, the management control device 50 may transmit a signal indicating that there is a small amount of inconsistency, a signal indicating that there is a large amount of inconsistency, a signal indicating that there is no inconsistency, and/or a signal indicating an amount of inconsistency to a backyard, when there is a difference between the actual liquidation amount and the calculated liquidation amount. In addition, a display device may be installed in the backyard, and contents of the signal received from the management control device 50 may be displayed on the display device.
